Description

TECHNICAL FIELD

The disclosure relates to the field of mobile communication technologies, particular to a method and device for processing an incoming message of a multimode controller which interacts with a Base Station Controller (BSC), a Radio Network Controller (RNC), other multimode controllers and the like, and a multimode controller.

BACKGROUND

At present, more and more telecommunication equipment manufacturers release multimode controllers in which 2G and 3G are common mode, and the multimode controller enables 2G and 3G services to be integrated, so that an operator only needs to buy a set of equipment to be able to support both 2G services and 3G services, and when the equipment is used as a 2G single mode controller in an early stage and the 3G service needs to be provided in a later stage, to also be able to directly use as a multimode controller, so as to greatly decrease equipment cost of the operator; therefore, the multimode controllers are attracted more and more extensive attention.
The multimode controller generally needs to support characteristics of all interfaces in 2G or 3G single mode, such as Abis interfaces, lub interfaces, lur-g interfaces, lur interfaces, A interfaces, luCS interfaces, luPS interfaces, Gb interfaces, and the like. For example, network interfaces of a multimode controller embody an lur-g attribute when interacting with a 2G BSC, and the network interfaces of the multimode controller embody an lur attribute when interacting with a 3G RNC.
In the single mode, an lur interface protocol stack is shown in Fig. 1, an lur-g interface protocol stack is shown in Fig. 2, and wireless control planes of the lur and lur-g interfaces both use a Signalling Connection Control Part (SCCP) protocol to bear wireless signalling. The multimode controller can realize that 2G and 3G are common mode, in terms of realization probability and cost saving, a software platform and a hardware platform should be shared as soon as possible, so in an incoming signalling procedure, a multimode controller based on sharing an SCCP protocol module should be relatively reasonable implementation.
However, in the prior art, Sub-System Numbers (SSNs) of upper users corresponding to the SCCP all are Radio Network Subsystem Application Part (RNSAP) on the lur and lur-g interfaces, for an SCCP protocol module, it cannot distinguish under a multimode only by the SSN whether a message received by the SCCP protocol module is an lur service or an lur-g service, which results in that incoming messages cannot build a correct corresponding relationship with target service users in an initial stage, increases a time delay for processing messages, and thus reduces use reliability of the multimode controller.
US 2008/207230 A1 discloses a multi-mode communication system that the multi-mode communication system uses a first mode among a plurality communication modes for accessing a first mobility control entity (MCE) among a plurality ofMCEs, and communicates data with the first MCE. The multi -mode communication system receives a paging request that has been transmitted from a multi-mode control entity (MMCE) for accessing a second MCE from the first MCE and analyzes the paging request, and puts the first mode into a sleep mode and a second mode for accessing the second MCE into an awake mode based on the analysis. Subsequently, multi-mode UE accesses the second MCE by using the second mode in the awake mode.
US 2010/3061336 A1 discloses a method for acquiring/updating information in the case of a handover between heterogeneous networks that includes: a) requesting first control information, associated with a new access point detected by a link scanning, from a network entity for providing information associated with a specific network; b) acquiring the requested first control information and second control information supplied from the new access point; and c) performing a connection to the new access point according to the first control information and the second control information.

DETAILED DESCRIPTION

The solution of embodiments of the disclosure is to add a protocol enhancement module between an SCCP protocol module and RNSAP protocol modules, to process an incoming message received by a multimode controller, to obtain a service standard type of the incoming message, and to send the incoming message to a RNSAP protocol module with a corresponding standard on a wireless control plane to process.
The disclosure mainly describes processing procedures above an SCCP protocol layer based on current lur-g and lur standard protocol interface protocol stacks, and does not change other transmission-related protocol processing processes under the SCCP protocol layer in a standard protocol stack.
In following embodiments, the solution of the disclosure is illustrated by dual mode of Wideband Code Division Multiple Access (WCDMA)/Global System for Mobile Communications (GSM), and dual mode or multimode of other standards, for example, a combination of any two or more standards of existing wireless communication standards, such as GSM, Code Division Multiple Access (CDMA), WCDMA, Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) and the like, or other subsequent evolved wireless communication standards, such as TD-SCDMA/GSM dual mode, WCDMA/CDMA/GSM multimode or the like, wherein at least two standards need to utilize an SCCP protocol incoming processing process, may refer to description of the disclosure.
As shown in Fig. 3, one embodiment of the disclosure proposes a method for processing an incoming message of a multimode controller, and the method includes:

Step S101: a multimode controller receives an incoming message from an abutting network element, and parses the incoming message to construct an N-primitive message.
At first, the multimode controller receives the incoming message from the abutting network element, and an SCCP protocol module of the multimode controller parses the incoming message to construct the N-primitive message, wherein the N-primitive message includes transport layer information such as SSN, OPC (Origination Point Code, that is, an abutting network element signalling point sending the message), DPC (Destination Point Code, that is, a local end signalling point) and other information associated with a transport layer, if the SSN is an RNSAP, then the SCCP protocol module sends the N-primitive message to a protocol enhancement module.
Step S102: a service standard type of the incoming message is obtained according to the N-primitive message.

In the step, the service standard type of the incoming message is obtained by the protocol enhancement module according to the N-primitive message, wherein obtaining the service standard type of the incoming message according to the N-primitive message can be completed in a transport network layer (first implementation), and also can be completed in a wireless network layer (second implementation), that is, the protocol enhancement module can belong to a transmission network user plane of the transport network layer together with the SCCP protocol module, as shown in Fig. 3a, and also can belong to a control plane of the wireless network layer together with RNSAP protocol modules, as shown in Fig. 3b. For the first implementation, the protocol enhancement module and the SCCP protocol module belong to the transport network layer, and the protocol enhancement module can obtain the related transport layer information from the N-primitive message, wherein the transport layer information includes SSN, OPC, DPC and other information, a network element corresponding to a signalling point in the transport layer information is of a standard attribute, which can be obtained by a local end when docks with an abutting network element, for example, whether the abutting network element is a 2G BSC or a 3G RNC, so the corresponding standard type can be obtained according to the standard attribute of the network element corresponding to an origination signalling point and/or a destination signalling point in the transport layer information.
For the second implementation, after the SCCP protocol module receives the incoming message, if the SSN is the RNSAP, then the SCCP protocol module sends the N-primitive message to a wireless network control layer according to the standard N-primitive message between the SCCP and the RNSAP, and the protocol enhancement module in the wireless network control layer obtains an RNSAP message from the N-primitive message sent from the SCCP to the RNSAP, and pre-decodes the RNSAP message. Information such as a cell number, an information type, a target RNC ID and the like can be obtained by decoding the RNSAP message, for example, the cell number is unique, whether the RNSAP message being of the 2G standard or the 3G standard is certain, therefore that the target RNSAP message is which standard service can be determined according to the de-coded result. After obtaining the service standard type of the incoming message, the incoming message is sent by the protocol enhancement module to the RNSAP protocol module with a corresponding standard to process. Each standard service has its own protocol module, there are multiple RNSAP protocol modules according to different standard types, and each RNSAP protocol module with the corresponding standard processes an N-primitive message corresponding to the standard.
Step S103: corresponding processing is performed on the N-primitive message according to the service standard type.
Corresponding standards of the N-primitive messages are performed by different standards of RNSAP protocol modules.
As shown in Fig. 4, corresponding to the above-mentioned first implementation of obtaining the service standard type, Step S102 includes:

Step S1021: transport layer information is obtained by parsing the N-primitive message.
The transport layer information includes: SSN and OPC and/or DPC.
Step S1022: the service standard type of the incoming message is obtained according to the transport layer information and a standard attribute table.

The standard attribute table includes: local end signalling points and thereof standard attribute fields, and/or opposite end signalling points and thereof standard attribute fields; or the standard attribute table includes: local end signalling point code, opposite end signalling point code, and corresponding network interface type fields; or the standard attribute table includes: local end signalling point code, opposite end signalling point code, corresponding network interface type fields, and standard attribute fields of local or opposite ends.
The signalling points in the transport layer information correspond to local end network element signalling points and opposite end network element signalling points respectively. The standard attribute table includes local end signalling points and thereof standard attribute fields. For example, a multimode controller is configured with two signalling points such as a signalling point 1 and a signalling point 2, wherein the signalling point 1 is of a 2G standard attribute and the signalling point 2 is of a 3G standard attribute. When the DPC of a message which is received by the local end is the signalling point 2, it can be obtained from inquiring the standard attribute table that the signalling received is a 3G service; and the standard attribute table can further include local end network element signalling point fields, opposite end network element signalling point fields, corresponding network interface type fields and other fields. For example, the lur interface is determined according to the OPC and DPC in the transport layer information, and the signalling received is determined as a 3G standard service directly; and the standard attribute table can further include local end network element signalling point fields, opposite end network element signalling point fields, corresponding network interface type fields, opposite end network element signalling point standard attribute fields and other fields, for example, by determining that the network interface is the lur-g interface as well as then based on that the standard type corresponding to the OPC (source signalling point sending the message) is of a 3G standard, it can be determined that the signalling received is a 2G standard service.
As shown in Fig. 5, corresponding to the above-mentioned second implementation of obtaining the service standard type, in the embodiment, Step S102 may include:

Step S1023: an RNSAP message in the N-primitive message is pre-decoded.
Step S1024: the service standard type of the incoming message is obtained according to a pre-decoded result.

The whole implementing flow of the embodiment is described below for two implementation of obtaining the service standard type corresponding to Fig. 4 and Fig. 5 respectively.
Taking RNSAP protocol modules of 2G and 3G standards (that is, a GSM RNSAP protocol module and a WCDMA RNSAP protocol module) as an example, the whole implementing flow of the embodiment is described in detail as follows.
Example one: taking a dual-mode controller receiving a CR message from an abutting RNC as an example, an SCCP protocol module parses the CR message to construct an N-primitive message. If the CR message does not include a Calling address field, then one Calling address field can be filled in after obtaining OPC information by a layer 3 signalling link protocol layer (such as an MTP3B layer, or an M3UA layer or the like) which receives the CR message. A Called address field in the N-primitive message includes transport layer information such as DPC, SSN and the like, and the Calling address field includes transport layer information such as OPC and the like. The SCCP protocol module can also add the OPC and DPC information obtained from a transmission signalling layer into the standard N-primitive message directly. When finding that the SSN is an RNSAP, the SCCP protocol module sends the SSN to a protocol enhancement module. The protocol enhancement module can obtain, by inquiring the standard attribute table according to the transport layer information OPC and DPC in the N-primitive message, that the OPC (opposite end network element signalling point) corresponds to a network element of 3G attribute and the DPC (local end signalling point) corresponds to a network element of 2G attribute, therefore the CR message is a 2G standard service; and the protocol enhancement module can further directly determine, directly according to that the DPC (local end signalling point) corresponds to a network element of 2G attribute, that the CR message is a 2G standard service. The protocol enhancement module sends the N-primitive message to the GSM RNSAP protocol module to continue to process.
After an SCCP connection is established, the SCCP protocol module has established a correct corresponding relationship of logic entities with the GSM RNSAP protocol module, at this moment, the SCCP protocol module can participle in processing flows no longer, and an incoming message associated with the SCCP connection can be sent to the GSM RNSAP protocol module at the SCCP protocol module.
Example two: taking a dual-mode controller being configured to a single 3G controller as an example, the dual-mode controller receives a UDT message from an abutting RNC, an SCCP protocol module parses the UDT message to construct an N-primitive message. SSN and DPC information can be obtained from a Called address in the UDT message, and OPC information can be obtained from a Calling address in the UDT message directly. A protocol enhancement module can obtain, according to the transport layer information OPC and DPC in the N-primitive message, that the OPC (opposite end network element signalling point) corresponds to a network element of 3G attribute and the DPC (local end signalling point) corresponds to a network element of 3G attribute, therefore the UDT message is a 3G standard service, and the protocol enhancement module sends the standard N-primitive message to the WCDMA RNSAP protocol module to continue to process.
Taking RNSAP protocol modules of 2G and 3G standards (that is, a GSM RNSAP protocol module and a WCDMA RNSAP protocol module) as an example, the whole implementing flow of the embodiment is described in detail as follows.
Example one: taking a dual-mode controller receiving a CR message from an abutting RNC as an example, an SCCP protocol module parses the CR message to construct an N-primitive message, and sends the N-primitive message to a protocol enhancement module in a wireless network control layer, and the protocol enhancement module pre-decodes an RNSAP message in the N-primitive message, wherein the RNSAP message is a wireless link establishment request message of the lur interface, in which has an ID of a cell which is of a 2G standard, therefore the incoming message is a 2G standard service, and the protocol enhancement module sends the N-primitive message to the GSM RNSAP protocol module to continue to process.
Example two: taking a dual-mode controller being configured to a single 3G controller as an example, the dual-mode controller receives a UDT message from an abutting RNC, an SCCP protocol module parses the UDT message to construct an N-primitive message, and sends the N-primitive message to a protocol enhancement module in a wireless network control layer, and the protocol enhancement module pre-decodes an RNSAP message in the N-primitive message, wherein the RNSAP message is a paging message, in which an ID of a cell which is of a 3G standard is included, therefore the incoming message is a 3G standard service, and the protocol enhancement module sends the N-primitive message to the WCDMA RNSAP protocol module to continue to process.
In addition, the protocol enhancement module is an independent module listed individually for functionally distinguishing an original standard protocol module, in a specific implementing process, the protocol enhancement module can also be implemented by integrating functions of the protocol enhancement module into an SCCP protocol module, and it needs to modify a part of incoming processing procedure of the SCCP protocol at this moment; the protocol enhancement module can further be implemented by integrating functions of the protocol enhancement module into an RNSAP protocol module, specifically, the SCCP sends all incoming messages to a RNSAP protocol module with a certain standard, the RNSAP protocol module with certain standard forwards, after determining all standard types of all incoming messages, the incoming messages to corresponding standards of RNSAP protocol modules to process. Distinguishing standards and forwarding functions of the protocol enhancement module in the embodiment of the disclosure can further be implemented outside the standard protocol modules or by modifying the standard protocol modules.
In the embodiment, by adding the protocol enhancement module between the SCCP protocol module and the RNSAP protocol modules to process the N-primitive message received by the multimode controller, the service standard type of the incoming message is obtained, and it is realized that the N-primitive message is sent to the RNSAP protocol module with the corresponding standard on the wireless control plane to process. Wherein, both the protocol enhancement module and the SCCP protocol module are multiplexed by the multimode controller, which not only saves software maintenance cost of the multimode controller, but also makes up shortages of current SCCP and RNSAP protocols when supporting the multimode controller, and realizes a function of distributing signalling according to standards. Furthermore, when being only configured as a single mode or presenting in the manner of multimode, the multimode controller needs not to be modified functionally, and can accurately forward a signalling to a corresponding standard of wireless network control service layer to process.
As shown in Fig. 6, the disclosure proposes a device for processing an incoming message of a multimode controller, which includes: an SCCP protocol module 601, a protocol enhancement module 602, and multiple different standards of RNSAP protocol modules 603, wherein:

the SCCP protocol module 601 is configured to receive an incoming message from an abutting network element, and parse the incoming message to construct an N-primitive message;
the multimode controller receives the incoming message from the abutting network element, and the SCCP protocol module 601 parses the incoming message to construct the N-primitive message, which includes transport layer information such as SSN, OPC (abutting network element signalling point sending the message), DPC (local end signalling point) and other information associated with a transport layer, if the SSN is an RNSAP, then the SCCP protocol module 601 sends the N-primitive message to the protocol enhancement module 602;

For the first implementation, the protocol enhancement module 602 and the SCCP protocol module 601 belong to the transport network layer, and the protocol enhancement module 602 can obtain the related transport layer information from the N-primitive message, wherein the transport layer information at least includes SSN, OPC, and/or DPC and the like, and can obtain the service standard type of the incoming message according to the transport layer information and the standard attribute table.

For the second implementation, after the SCCP protocol module 601 receives the incoming message, if the SSN is the RNSAP, then the SCCP protocol module 601sends the N-primitive message to a wireless network layer, and the protocol enhancement module 602 in the wireless network layer obtains the RNSAP message from the N-primitive message sent by the SCCP protocol module 601, and pre-decodes the RNSAP message, accordingly, that the RNSAP message is which standard service can be determined according to the de-coded result, that is, the service standard type of the above incoming message can be obtained.
After obtaining the service standard type of the incoming message, the incoming message is sent by the protocol enhancement module 602 to the RNSAP protocol module 603 with the corresponding standard to be processed by the RNSAP protocol module 603 with the corresponding standard. Each standard service has its own protocol module, there are multiple RNSAP protocol modules according to different standard types, and each RNSAP protocol module with corresponding standard processes an N-primitive message corresponding to the standard.
